Coolant Flush question
I wanted to get my coolant flushed in my 96 LT4 and I don't feel like messing with it myself. Does anyone suggest any of the major shops for this such as a Firestone, Jiffy Lube etc. Has anyone had any experience with them. I figure they do them all the time and should guarantee their work, right? How about the Chevy Dealer? Any suggestions on cost and quality would be appreciated. Thanks.

Pappy, why bother?
There is a drain plug on the lower Right hand side of the radiator. Drain it out and refill it with Good anti freeze and Deionized water from the Grocery store. (sometimes called distilled water)
I just save you $70

To get a 100% flush in the LT4, you also have to drain the block and let all the junk out.
